Phase conjugation via multiple gratings in photorefractive crystals Academic Article uri icon

abstract

  • We consider phase conjugation via degenerate four-wave mixing in photorefractive crystals when more than one grating mechanism is operative. A method for exact solution of the steady-state wave equations which include pump depletion is presented. It is discovered that equal-strength multigrating operation does not allow signal amplification. © 1988 The American Physical Society.
